(Lancaster, MS.) — Sheriff's deputies in Lancaster were investigating the discovery of a hidden cellphone camera recording video inside the ladies bathroom at a Starbucks in Lancaster on Thursday.

A woman, who asked not to be identified, told KTLA that her 5-year-old son made the discovery around 10:30 a.m. at a downtown Starbucks.

"My son used the restroom first and I used the restroom after him," she said. "I noticed he was staring at the sink a little bit perplexed. I asked him what was wrong and he said, 'Mommy, why is there a phone under there.'"

When she looked under the sink, the woman saw a cell phone propped up by paper towels with the camera pointing toward the toilet.

She immediately notified employees who contacted the sheriff's department.

"The deputies discovered that the cellphone was running in a video-recording motion, said Lt. Joseph Fender with the Lancaster Sheriff's Station.

"It's such a violation of privacy," the victim said. "Not only of mine, but my son."

It was not clear where the video was being sent or how long the phone may have been recording.

"They were able to get some type of surveillance video from the location, however I don't know what the contents of the video are at this time," Fender said.

Starbucks spokesman Jaime Riley reached out to KTLA saying, "We are disturbed by this incident and take our obligation to provide a safe environment for our customers and partners (employees) very seriously. Our store partners took swift action as soon as they became aware of the incident by immediately alerting the Sheriff's Department of the situation."
